By dramatically shifting energy metabolism towards ketogenesis and fatty acid oxidation, ketogenic diets are likely to have a profound effect on mitochondrial function. However, despite the rapidly growing amount of research on ketogenic diets and their effects on various disease states, only a small amount of this research has focused on mitochondrial function or oxidative stress. The well-established increase in fat oxidation induced by a ketogenic diet [7, 8] clearly indicates prominent connection with mitochondrial function and, in turn, oxidative stress and mitohormesis [5, 6, 9]. Therefore, the purpose of this review is to describe the current, but limited, understanding of how ketogenic diets may affect mitochondrial function and resistance to oxidative stress, particularly within the context of extending human healthspan.
The low carbohydrate content of the ketogenic diet prevents blood sugar spikes and stabilizes insulin levels. Chronically high insulin levels and the disrupted incretin signaling (gut derived molecules) lead to insulin resistance over time (pre-diabetes). This means that our cells are not willing to take up vast amounts of glucose anymore and more and more insulin is needed for glucose uptake – a vicious cycle.
While there are some differences in opinion, depending on who you ask, regarding the best approach to very low-carb dieting, studies consistently show that the ketogenic diet (also called the keto diet) produces not only substantial weight loss for a high percentage of people who adhere to it, but also other important health benefits such as reductions in seizures, markers of diabetes and more.

It looks and smells beautiful when baking. The bottom of my loaves is heavy and dense. The top rises and makes an air pocket. As a result, it’s just not really pleasant to eat with it being so dense and solid even though it tastes good. The few good pieces at the very ends were yummy. I really don’t know what to do. Almond flour is expensive to be going through it like this. 🙁
Hi Maria! I just want to say thank you for this bread recipe! It is awesome! It took me 4 times to get the technique down, but it works with both the Jay Rob psyllium and the bulk I get at my local store (which turns it purple). I watched your video and realized I was doing two things wrong… I was over-mixing and then I was squishing or handling the dough too much. With a little shorter mixing time, like you show on your video, and with light hands “shaping” the dough to fit in the pan, I have met with success! I also picked up the same size pan you use at the grocery store for about $5. This is the only low-carb gluten-free bread my daughter will eat. She loves it! Thanks again!
I have great respect for Harvard Medical School. I notice that they support their readers posting comments and I am most appreciative of the article and all the many thoughtful comments by the readers. The readers seem to have the most expertise here and I hope that the doctor who wrote the article will think long and hard about the comments by readers. After 35 years of clinical practice in mental health, I notice that all issues of emotion involve medical issues, nutrition, and the gut bacteria. I would say that these issues and all of the executive brain functions seem to improve with ketogenic principles. For those that apply it in a flexible and smart manner, it appears to improve every area of their lives. I strongly encourage the author of the article to take one class via The Institute for Functional Medicine. If he is open to more learning he can take more classes and get certified. I’m sure a fine doctor, he will be an even better doctor and personally healthier, if he gets more training. Are we all open to new learning(especially us healthcare providers)?
We are brazilian, living in Brazil. My daughter, Isabel, 21y. o., born in 1996, has syndrome of deficiency of Glut1. She was diagnosed around her first year of life. At that time her baby bottle, her begining diet meal, was 50ml water plus 50ml oil plus vitamin. Since then, which means, for 20 years, she is under this diet. For almost 18 years under 4:1 proportion. At this right moment 3:1. The only problem she had since started the diet were kidney stones in 2002. Nothing else. Grateful to the diet she doesn’t take any kind of medicine to avoid seizures. Her health is perfect, no colesterol at all. We are at your will for any issues related to her health.
In addition to the downstream bioenergetic and antioxidant signaling induced by sirtuins, they directly facilitate ketogenesis and β-oxidation. SIRT1  and SIRT3  deacetylate 3-hydroxy-3-methylglutaryl CoA (HMG CoA) synthase, which is the rate-limiting enzyme for ketogenesis , resulting in increased levels of β-hydroxybutyrate . In addition, SIRT3 deacetylates and increases activity of long-chain acyl-CoA dehydrogenase (LCAD) , which participates in β-oxidation and therefore supports ketogenesis. SIRT3 has a similar influence on medium-chain acyl-CoA dehydrogenase (MCAD) as well . Since sirtuins facilitate ketogenesis, which then facilitates sirtuin activation, nutritional ketosis may promote, to some extent, a feed-forward cycle of sirtuin activity.
A little more than 9.2% of pregnant women have gestational diabetes. It is very common that all women are tested during their pregnancy. If you haven’t yet, bring it up to your physician’s attention. The cause is really unknown, but doctors believe that it is because the extra hormones that are released during pregnancy hinder the insulin sensitivity and increase the need for more insulin. It is very important to keep blood sugar levels under control because high blood sugars can lead to complications such as:
You’ve got a few options here. Erythritol (Lakanto is awesome here), Xylitol (non-corn though to avoid tummy troubles!) and allulose are my top choices (no aftertaste at all!). Pyure is also a good one for muffins and quick breads, particularly if you’re trying to limit your sugar alcohol consumption (it’s added stevia makes it twice as sweet as sugar… i.e. you add half!).
More specific to mitochondrial function, treatment with BHB + ACA (1 mM each) has decreased O2•− production in isolated rat neuronal mitochondria following glutamate exposure . This occurred in conjunction with decreased NADH levels, suggesting that ketones may additionally decrease mtROS production by enhancing electron transport along the mtETC after NADH oxidation and, in turn, decreasing mitochondrial Δp and associated O2•− production. The observed decrease in mitochondrial O2•− production occurred independently of glutathione , but in isolated and stunned hearts from guinea pigs, treatment with 5 mM ACA increased GSH and the NADPH/NADP+ ratio , suggesting that glutathione may be involved to some extent.

I love how simple this recipe is and how quickly they bake! My oven is broken and only goes to 350, so I had to adjust the bake time and think I slightly overbooked them as they were a bit dry. I followed some of the comments’ recommendations and used half egg whites and half whole eggs (I made 4) and did not find them eggy. They were light and fluffy, but a bit bland. I added rosemary to 2 and garlic powder, cheddar cheese and parsley to 2. I just eyeballed the additions and found them bland. Next time I will add more herbs/cheese. I did butter them and found they soaked up the butter – again maybe because they were dry? I will definitely make these again. Thanks again for a great quick and easy recipe!
I so miss bread fresh from the oven (I’m going to be adding the yeast)! You are absolutely correct about beaten egg whites creating air pockets. My family has always made buttermilk pancakes from scratch and we always separate the eggs, beat the whites to soft peaks and fold them in at the last minute. The pancakes rise beautifully! Have you tried this with your keto pancakes?

Add yeast and maple syrup (to feed the yeast, see notes) to a large bowl. Heat up water to 105-110°F, and if you don't have a thermometer it should only feel lightly warm to touch. Pour water over yeast mixture, cover bowl with a kitchen towel and allow to rest for 7 minutes. The mixture should be bubbly, if it isn't start again (too cold water won't activate the yeast and too hot will kill it).
I am disappointed with my first effort but remain undaunted. I did not use the J Robb psyllium but did grind it up as finely as I could and otherwise followed the recipe exactly. I am an experienced baker so I’m not giving up and will try using less water next time. I want to use as many ingredients as I can find in my small town in order to vote with my dollars for more healthy foods so I will try a few more times before special ordering.
